UNITED STATES PATENT OFFICE.

JOHN FRANKLIN MONUTT, OF CINCINNATI, OHIO.

MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 692,064, dated January 28, 1902.

Application filed July 3, 1901.

T0 at whom it may concern:

Be it known that I, JOHN FRANKLIN Mo- NUTT, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Motor-Vehicles; and I do hereby declare the following to be a full, clear,and exact description ofthe inventionisuch as will enable others skilled in the art to which it appertains to make and use the same.

Thisinvention relates to automobile frames and the connection between the equalizinge gear and the transmission-train.

The primary object is to so construct the frame that it will be strong and durable without using braces or directconnections between the axles, and the gearing-wheels will be kept in proper and certain alinement, preventing any displacement by the torque of the pinion driving the difierential.

A further object is to provide a connection between the equalizing-gear and the transmission-train which willbe strong and substantial'ahd avoid all noise, jerk, or sudden pull on the driving mechanism as the carriage-frame rises and falls in going over rough roads.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is a side elevation, parts being shown in dotted lines. Fig. 3 is a front end View with parts broken away.

Referring to the drawings, 1 designates the two side bars of the frame, each at its rear end having an upper overhanging downwardly-curved arm 2 and a lower upwardlyextended arm 3. Through the ends of these two arms is passed a tube or rod 4, which is arranged transversely of the frame. To a lower short arm 5 is jointed a brace-bar 6, which at its other end is pivoted to an arm-7, depending from a bearing-block 8. Within the two bearing-blocks fits the axle 9 of the rear carrying-wheels 1O.

12 designates the rear springs, of'elliptical formation, bolted to blocks 13 on the ends of tube 4 and to the bearing-blocks 8 in direct vertical line.

At the front of the frame each side bar is equipped with a brace-bar 14, corresponding Serial No. 67,049| (No model.)

to the brace-bars 6. They arejointed to short depending arms 15 bya cross-tube 16 and at their lower forward ends are pivotally connected to the front axle, to which also is connected the lower branch of the front spring 17, this latter being in the form of a reversed elliptic arranged transversely of the frame. The extreme forward end of each side bar is carried upward at 28 and secured to the ends of the upper branch of spring 17. construction the alinement of the wheels is made certain, and the frame is strong and durable and is free from all braces or connections directly between the axles of the front and rear carrying-wheels. 'lhe brace-bars 6 and springs 12 provide against any undue strain by the torque of the pinion driving the differential, which is taken up by the bearingblock 8 adjacent thereto.

19 is the differential or equalizing gear.- wheel on the rear axle. It is driven by the spur-pinion 20, and 21 is a gear-wheel driven by the gear-wheels 22 and 23 of the transmission-train of the motor. The shafts of pinion 20 and wheel 21 are substantially parallel with the rear axle and are connected by a flexible shaft'24, having suitable universal joints 25, by which the said pinion and wheel are positioned in line whenthe carriagehas its normal load; but the joints and flexible shaft will allow of any elevation or depression or other displacement of the gear-wheel 21 within the range of movement allowed by the springs. Thus in lieu of the ordinary chain or beveled gear universal-joint device I employ strong and substantial spur-gearing, thereby eliminating all jerks or sudden pull on the driving mechanism as the carriageframe moves up and down in traveling over rough ground.

I claim as my invention- 1. In a m otor-vehiele, the combination with the carrying wheels, their axles, and the springs, of the longitudinal side bars, forward and rearwardly extended brace-bars secured each at one end to one of the side bars and at its other end having a-pivot connection with one of the axles, said side bars being connected to said springs in vertical line with the connections between the brace-bars and axles, substantially as set forth.

2. In a motor-vehicle,the combination with By this the carrying-wheels, their axles, and the springs mounted above the latter,of the frame having longitudinal side bars, forward and rearwardly extended brace-bars secured to said side bars, connections between said brace-bars, the axles and the springs, and connections between said side bars and the springs, substantially as set forth.

3. In a motor-vehicle, the combination with the carrying-wheels, their axles, and the springs mounted above the latter, of the longitudinal side bars having forward and rearward extensions connected at their ends to said springs, forward and rearwardly extended brace-bars secured to said side bars, and connections between said brace-bars, the axles and the springs in vertical line with the connections between the side bars and the springs, substantially as set forth.

4. In a motor-vehicle, the combinationwith the carrying-wheels, their axles, the two rear springs and the front spring mounted above the latter, of the side bars, a cross rod or tube secured to said side bars and to the two rear springs, a second cross rod or tube between said side bars, said latter cross rod and the side bars being connected to the front spring, substantially as set forth.

5. In a motor-vehicle, the combination with the carrying-wheels, their axles, and the rear springs, of the side bars having rearwardlyextended arms,connections between said arms and the rear springs, rearwardly-extended brace-bars secured to said side bars, and means pivotally connecting said brace-bars to said springs in line with the connection of the rearwardlyextended arms, substantially as set forth.

6. In a motor-vehicle, the combination with the carrying-wheels, their axles, and the rear springs, of the side bars having rearwardlyextended arms, a cross-rod to which said arms are secured, means connecting said cross-rod to said springs, rearwardly-extended bracebars secured to said side bars, and bearings for the rear axle having depending arms to which said brace-bars are pivotally connect- 'ed, substantially as set forth.

7. In a motor-vehicle, the combination with the carrying-wheels, their axles, the two rear springs and the front spring, of the side bars having rearwardly-extended arms, a cross-rod to which such arms are secured, said cross-rod being attached to said rear springs, the rearwardly-extended brace-bars secured to said side bars, bearings for said rear axle having depending arms to which said brace-bars are pivoted, and connections between said side bars, the front spring and the front axle, substantially as set forth.

8. In a motor-vehicle, the combination with the carrying-Wheels, theiraxles, and the front and rear springs, of the side bars havingforward extensions secured to said front spring, forwardly-extended brace bars secured to .said side bars and the front axle and the front spring, and means connecting said sidebars tosaid rear springs and to the rear axle, substautially as set forth.
